Application filed. November 23, 1916.

1 b all whom it may concern:

Be it known that I, GEORGE F. MCCAHEY, a citizen of the United States,and resident of the city of Providence, in the county of Providence andState of Rhode Island, have invented certain new and useful Improvementsin Carriers for Braiding-Machines, of which the following is aspecification.

This invention relates to an improvement in carriers for braidingmachines, and the primary object of the invention is to provide a stopon the top of the standard to positively prevent the top weight or latchfrom being accidentally thrown from the standard even while the carrieris running at a high velocity.

A further object of the invention is to leave one side of the standardstraight to its upper end and cut away on its opposite edge for a shortdistance downward from its upper end whereby this latch may be appliedto the standard at a point below the upper stop lug by a laterallyrotating motion.

The invention further consists in the provision of a bottom or tensionweight also slidable on the standard provided with a finger or extensionfor engaging a portion of the top latch to prevent the latter fromrotating on the standard when both are in raised position.

It is found in practice that where the top latch is passed onto thestandard over the end thereof, that the short laterally extending bossmust be so small that it fails to serve as a positive stop to preventthe latch from being thrown off therefrom in the same direction it wasapplied, thereby eliminating the traveling speed of the carrier.

To obviate this serious difiiculty and prevent the latch from beingthrown upward off the end of the standard, I have cut away the side ofthe standard to permit this latch to be passed onto the standard byalateral rotary motion and then I provide means on the bottom or tensionweight for preventing the latch from rotating on the standard when inraised position.

A further advantage of my improved construction is that the latch isprovided with a continuous or unbroken bearing on the yarn on the spool,the cut away portion of the standard being on the opposite side or theside which does not receive the strain.

With these and other objects in view, the invention consists of certainnovel features Specification of Letters Patent.

of construction, as will be more fully described, and particularlypointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation showing my improved standard with a spoolmounted on the spindle and the tension weight and latch mounted on thestandard, the weight being in the down position.

Fig. 2 illustrates the bottom weight as having been raised to engage andraise the latch, also showing the finger on the tension weight engagingthe boss on the latch to prevent the latter from rotating while inraised position.

Fig. 3 is a view of the rear side of the standard showing the one edgecut-away, and representing the latch in dotted lines as being applied tothe standard.

Fig. is a rear view of the latch showing the lateral extension thereofdesigned to be engaged by the projection on the bottom weight to preventrotation of the latch.

Fig. 5 is a plan view showing the stand ard in section on line H of Fig.2 through the reduced portion thereof, also representing the latch inthe act of being applied to the standard at its reduced point by a lateral rotating motion, the end of the spool also being shown.

Fig. 6 is a rear view of the bottom or yarn tension weight.

Referring to the drawings, 10 designates the carrier frame having agroove 11 adapted to be run and be guided in the usual raceway, saidcarrier frame being also provided with a spindle 12 on which a yarnspool 13 is mounted. The upper end or head of the spool 14 is providedwith the usual ratchet teeth 15.

This carrier frame is provided with a standard 16 having the usual leadeve 1'. in its upper end and a guide eye 18 near its middle portion. Thestandard is also provided with an exceptionally large forwai'dlyprojecting stop or lug 19 at its upper en Another feature in theconstruction of the standard is that it is provided with one straightedge 20 extending up to this guide eye and lip while its opposite edgeat 21. see Figs. 3 and 5, is cut awav for a short distance downward toprovide a narrow neck portion for the purpose of permitting the tensionweight 22 and also the latch 93 to be positioned thereonto.

An essential feature of my invention is that the stop lip 19 is formedof asi/ie so large that the latch cannot be passed tlrei'eover onto thestandard for the reason that when the carrier is running a high we ofspeed the tension weight is thrown with great force against the latchwhich drii es it hard against this stop", and great tronlzile has beenexperienced with the old style carrier, where the latch is applied overthe end of the standard in throwing the latch over the lip, in whichcase the latch is so long in returning that'it permits the spool torotate several teeth and so allows the bottom weight to dropsufficiently to engage the stop lever an'dst'op the machine, but myimproved construction this stop lug so large that it must positivelyengage and limit the upward motion of this latch. Therefore in orderthat so large and positive a stop may be used, I am obliged to apply thelatch to the standard at a point below the top, which is accomplished byhooking one edge 23 of the latch around the straight edge of thestandard as illustrated in Fig. 5 and then to swing the opposite edge2-.t around through the cut-away portion of the standard after which itis permitted to slide down the standard into position to permit itstongue 25 to engage the ratchet teeth 15 on the spool.

In order to positively prevent this latch from rotating back again inthe direction to release itself while running, I have formed a laterallyextending boss 26011 one edge thereof and I have also provided a fingeror upwardly extending member27, on the upper end of the tension weight22, which finger is adapted to hook over or around the boss 26 when theweight is raised so as to positively prevent rotation of this latch whenin raised position as illustrated in Fig. 2.

I have shown and described one means by which this top latch may beprevented from rotating while in its up position but there are many waysofaccomplishing this object and any suitable means may be employed forthis purpose for preventing such rotating motion.

Another feature which is of importance is that the straight side edge ofthe standard produces a full length bearing for the working edge of thelatch, even when thrown upward and out of engagement with the spool.

This is not the case with the usual standard which is cut away on bothof its edges.

Having thus described one illustrative embodiment of my invention Idesire it to be understood that I do not wish to limit my self to theexact construction shown L11Cl described as the details may be changed(,epies of this patent may be obtained for five cents each, byaddressing the Commissioner of Patents,

without departing from the spirit of my invention, the scope of which isdefined by the appended claims. 5

I claim:

I I. A braider carrier comprising a f"ame having a standard withlongitudinally-chsposed guiding edges, a yarn tension weight slidabl'eon said standard, a latch having grooved edges with guiding flanges toslidably engage the guiding edges of said st andard, a head on the freeend of said standard of a size to prevent the passage of thel'atchthere'over, a section of one edge of said standard inmiedi'ately belowsaid head being remoi 'ed substantially equal to the length of saidguide hinge on the corresponding edge of the latch whereby said latchmay be cons nect'ed t'o an'd'disconnected from said stand ard by arotating mot-ion only, and means for preventing accidental disengagementof 7 said latch from said standard when carried upward by said tensionweight.

A carrier. for braid 1g machines comprising a frame having a spoolspindleand a standard, a sliding latch on said standard for engagingteeth 'on the spool, a lateral extension on theobody of said latch, ayarn tension weight also slidable on said standard, a stop lug on thestandard of a size to prevent the latch being removed over the-emlthereof, one edge of said standard being straight to provide a bearingfor the latch to the top of its stroke, said standard being reduced onits opposite edge to permit the latch to be app-lied thereto at a pointbelow said stop with a rotating motion, and an upward extension on oneedge of said weight. to engage said lateral-extension on the latch toprevent an unlocking rotativ'e movement of the latter when both areraised.

3. A carrier for braiding machines comprising a frame having a spoolspindle and a standard, a sliding latch on said standard for engagingsaid spool, a yarn tension weight also slidable on said standard, a stopat theend of said standard to prevent the latch from being thrown orotherwise removed thereover, one edge e: said standard being straightand its opposite edge cut away at a point just below said stop to permitready application of the latch to the stand- In testimony whereof Iailix my signature in presence of a witness.
